Once you have a startup CD with the same version of system files as the PC you're working on, configure your PC to boot from CD if it isn't already set up that way. It's a good idea to have an up-to-date, slipstreamed setup CD available in any case, as it simplifies all future installs and CD-based repairs. This kind of updated setup CD can be used on just about any XP installation. The solution here is to use a "slipstreamed" setup CD, which adds the newer files to your original setup CD.

You'll get a message to the effect that the version you're trying to upgrade is newer than the version on the CD.

The one catch is that if your setup CD is significantly older than your current Windows version, you may have file compatibility problems. The safest, surest way to resolve problems such as "Missing or corrupt HAL.DLL," "Invalid Boot.Ini," or "Windows could not start." is to boot the PC from an XP Setup CD and use the pristine, uncorrupted files and tools there to effect repairs. To save you time, we'll concatenate the instructio Enter The Recovery Consoleonsole ? Run "Attrib -H -R -S" on the C:\Boot.ini fileīut the first few times you try this repair, it makes sense to use the slightly longer but more certain "official" method, as outlined by Microsoft in a number of separate Knowledge Base articles. ? Boot from your XP Setup CD and enter the Recovery Console Once you know the process, it's actually quite straightforward and takes only a minute or two to run to completion.įor example, if you already have some knowledge of the commands involved, many "Missing or corrupt HAL.DLL," "Invalid Boot.Ini," or "Windows could not start." problems can be fixed with these five shortcut steps: This has the effect of removing and repairing any references to whatever invalid, missing, or corrupt startup information was preventing normal booting.Īs is true of so many technical topics, this one actually takes far longer to describe than to implement, so please don't be put off by any seeming complexity in this discussion.

If you know about this command and how to use it, you can potentially save yourself hours and hours of manually reinstalling or rebuilding a failed operating system. It can often easily fix "Missing HAL" and similar problems in just a minute or two. Then-doh!-I stopped thrashing and did what I should have done initially: I dug into the Microsoft Knowledge Base and learned about XP's built-in Rebuild command. I tried everything I could think of, but nothing worked. I tried renaming it all uppercase and then all lowercase. I tried copying a fresh version of the file to \Windows\System32. Why couldn't the operating system find it? I booted the PC, switched to the \Windows\System32 folder, and there it was: The HAL.DLL was already there.

For example, the first time I got a "Cannot find \Windows\System32\hal.dll" error message, I thought I'd be clever and replace the missing file via a simple Copy command from the Recovery Console. These problems can seem hard to get past. moving the operating system to a new hard drive), or after problems with dual- or multi-booting software, you may encounter seemingly intractable errors such as "Missing or corrupt HAL.DLL," "Invalid Boot.Ini," or "Windows could not start."

But sometimes, especially after major hardware failures or part swaps (e.g. Even in those rare cases when the operating system is badly damaged, you'll usually at least have the option of booting into the "Last Known Good" configuration, or to Safe Mode. It usually takes a lot to stop XP in its tracks. There's an easy fix for "Missing HAL.DLL," "Invalid Boot.Ini," and several other fatal startup errors, Fred Langa says.
